HEDDLE FRAME.

Application led March 10, 1923.

To all w 7mm, may concer/n Be it known that I, JACOB KAUFMANN, a citizen of the United States, residing at Elkins Park, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Heddle Frames, of which the following is a specification.

My invention relates to heddle frames for looms, and it has particular relation to the provision of improved means in such heddle frames for securing the heddle supporting bars against displacement in the frame. n

In the construction of heddle frames in which the end members, as Well as 'the top and bottom bars, are made of strips of Wood or similar material, considerable difficulty is ordinarily experienced in the provision of Suitable and eflicient means for securing the heddle supporting bars in proper position in the frame, particularly Where vthe frame is made as thin as possible, as is often required where the spac'eis limited. i

.The principal object, therefore, of my present invention is to provide a heddle frame, in which the end members, as Well as the top and bottom bars, are made of relatively thin strips of Wood or similar material, having improved means for securing the heddlesupporting bars in place, which will be inexpensive, yet efficient, and which Will require a minimum of labor in the con struction, arrangement and assembly thereof.

The nature and characteristic features of my invention will be more readily understood from the following description, taken in connection with the accompanying drawin s forming part hereof, vin Which: igure 1 is a side elevational view of a heddle frame embodying the main features of my present invention;

Fig. 2 is a fragmentary detail view, enlarged, artly in section, of one lcorner of the heddle frame' shown in Fig. 1, the same illustrating more clearly the details of the construction and arrangement of the improved means for securing 'the heddle supporting bar in place; and

Fig. 3 is an end elevation of the portion of the structure shown in Fig. 2.

Referring to the drawings, the heddle frame proper preferably'comprses top and bottom bars 5 and end members 6, all of which are preferably made of relatively thin Serial No. Y 624,170.

strips of Wood, the same being united to each other at the corners, by suitable mor tises or other preferred construction to prf vide a rigid frame.

The heddle supporting bars 7, with the lieddles 8 mounted thereon in the usual manner, are mounted kin the frame having their end portions extending through slots 9 ertending through the end members 6. The ends of the heddle supporting bars 7 project beyond the outer marginal edge of the end members 6 and are preferably apertured, as at 10, in said extending portions.

The securing device proper comprises a member 11, preferably made of spring steel Wire. One end of the member 11fhas a bent over extension 12, preferably provided With a sharpened end 13, so that the same may be forced or driven into the end member and there held by frictional engagement as clearly shown in Fig. 2 of they drawings. The end members 6 may be preliminar-ily bored or not for the reception of the extension 12 of the member 11, aci/fording to the nature of the material of the end members 6, as Will be readily understood. Adjacent the extension 12 of the member 11 is a portion 14: arranged substantially at right angles to the extension 12 and adapted to be seated in a recess 15 in the outer surface of the end member 6, the recess 15 extending along the outer surface of the end member 6 a suiiicient distance for the reception of the portion 14.-. The material of the member 11 is then bent outward at the end ot' the portion 14;, as shown at 16, and thence extends adjacent the outer surface of the end meniber 6, as at 17, finally terminating in a hooklike portion 18 Whichis adapted to engage the aperture 10 in the projecting end of the heddleV supporting bar 7, it being understood that, for the purpose of effecting said engagement ofthe hook-like portion 18 with the aperture 10, the free end of the mem ber 11 may be sprung, from the position shown in dotted lines in Fig. 2 of the drawing to that shown in full lines7 into operative engagement, as aforesaid, with the aperture 10 of the heddle bar 7.

It Will `be seen that there is thus provided a simple and eiiicient means for securing the heddle supporting bar against longitudinal displacement in the frame, which is so constructed and arranged as to `require a minimum of labor in the constriution and. assembly thereof in the framefbut which will. be quite efficient in its action. By seating the portion A of the securing member ll in the recess 15, the member 11 will be maintained against rotation about the which would otherwise be afforded by the portion 12 which is driven into the end member 6 and which is retained therein by frictional engagement. rIhus the member 11, vvill always be maintained in such position that no part thereof Will be permitted to extend beyond the side surfaces of the frame, and will thereby prelude the possibility of any portion of the securing member l1 fouling with adjacent frames or any portions thereof, during the reciprocation of the frames in the loom.

Having thus described the nature and characteristic features of my invention, what I claim as neu7 and desire to secure by Letters Patent is:

l. A heddle frame comprising top and bottom bars and end members, heddle supporting bars mounted in said frame extending through slots in the end members and having their ends projecting beyond the outer margins of the end members and having apertures provided in said projecting portions, securing` devices each adapted to engage one of said projecting end portions of the heddle supporitng bar and comprising a member made of spring Wire having one end thereof extending into the material of the end member and being retained therein by frictional engagement7 said mem# ber having a spring-like extension', the free end of said extension being provided With a hook-like portion adapted to engage the aperture in the heddle supporting bar, and means for preventing rotative movement of said securing mem-ber about the portion thereof which extends into the end member of the frame.

2. A heddle frame comprising topV and bottom bars and end members, heddle supporting bars mounted in said frame extending through slots in the end members and having their ends projecting beyond the outer margin of the end members and having apertures provided in said projecting portions, securing` devices mounted on the outer marginal edges of said end members each adapted to engage one of said projecting end portions of the heddle supporting bar and comprising a member made of spring Wire having one end thereof ex- Vtending` into the material of the end member and beine` retained therein b frictional i ,asi ,soa

engagement." said member having a spring like extension9 the free end of sai-fl extension being provided with a hook-like portion adapted to engage the aperture in the heddle supporting bar, and means for preventing rotative movement of said securing member about the portion'thereof which extends into the end member of the frame.

3. A heddle frame comprising top and bottom bars and end members made of thin fiat strips, heddle supporting bars mounted in said frame extending through slots in the end members and having their ends projecting beyond the outer margins of the end members and having apertures provided in said projecting` portions7 Securing devices mounted on the outer marginal edges of said end members each adapted to engage one of said projecting end portions of the heddle supporting bar and comprising a member made of spring Wire having'one end thereof extending into the material of the end member and being retained therein by frictional enga-gement, said member having another portion thereof seated in a recessl in the outer marginal edge of said end member to prevent rotative movement of said securing device, and having a Aspring-like extension, the free end of said extension being` provided with a hook-like portion adapted to engage the aperture in the heddle supporting bar.

4f. AY heddle frame comprising top and bottom bars and end members made of thin flat strips, heddle supporting bars mounted in said frame extending through slots in the end members and having their ends projeeting beyond the outer marginsof the end members and having apertures provided in said projecting portions, securing devices mounted on the outer1 marginal edges of; said end members each adapted to engage one of said projecting end portions of the heddle supporting bar and comprising a Vmelmber made of spring wire having one end thereof extending intothe material of the end member and being retained therein by frictional engagement, said member having an adjacent portion thereof seated in a recess in said end member to prevent rotative movement of said securing device, and having a spring-like extension7 the freeend of said extension being provided with a hook-like portion adaptedI to vengage the aperture in the heddle supporting'. bar.

ln testimony whereof,l I, have hereunto signed my name.
